Good idea, I didn't think about uploading them to the Open Source section. The original source is MPEG2. As far is quality goes. I can encode them to DIVX, MPEG 1,2,4 Real, Flash Video, QuickTime, etc. Quality is not dependent on the codec. I can encode using any of codecs above and get really good quality. Quality is dependent on how high a bit rate I want to use. I prefer to use mpeg 4 because I can get the best quality for the lowest bit rate, it's not propritary, it's ISMA standard, and it's editable. The archive MPEG4's, and I guessing about this, (don't get mad guys) are all done with single-pass encoding, meaning the movies are compressed at fixed bit rate. I use 2 pass encoding, so I'm able to get better image quality with smaller file sizes that don't have the artifacting (on the smaller mpeg4s) and crystilization type effect you get with the large editable mpeg4s. Compression is just as much an art as it is a science.

If you upload MPEG2 the Archive's server automatically make derivatives to MPEG1 and two bitrates of MPEG4. I would suggest you upload the MPEG2 versions, as that will fit in with the Feature Film and Prelinger section and it will be the best quality since derivative encodes will have additional artifacts.

Cool I can do that.
